Route with alternatives

Display route alternatives and what sets each one apart

SDK 1.0.0-rc.7

Each card says what sets its route apart: how far it drives alone, its main roads and what it adds or avoids against the selected route or the usual one.

maxAlternatives gets the alternatives in one request, each with its sections.distinct, so the distance takes no geometry work.
getImportantRoads names the roads within those sections, each once.
compareRoutes lists the ferries, tolls, jams and closures one route takes and the other doesn’t, the usual route asking for costModel: { traffic: 'historical' }.
setSectionFocus rings a route’s own roads, or what a chip names, as you point at it.
